The electrochemical nitrate reduction to ammonia reaction (NO3RR) has emerged as an appealing route for achieving both wastewater treatment and production. Herein, sub-nm RuOx clusters anchored on a Pd metallene (RuOx/Pd) are reported highly effective NO3RR catalyst, delivering maximum NH3-Faradaic efficiency of 98.6% with corresponding NH3 yield rate 23.5 mg h–1 cm–2 partial current density 296.3 mA at −0.5 V vs RHE. Operando spectroscopic characterizations combined theoretical computations unveil the synergy enhance energetics through mechanism hydrogen spillover hydrogen-bond interactions. In detail, activates NO3– form intermediates, while dissociates H2O generate *H, which spontaneously migrates RuOx/Pd interface via process. Further interactions between spillovered *H intermediates makes desorb from participate in intermediate hydrogenation, contributing enhanced activity NO3–-to-NH3 conversion.

Abstract With the development of renewable energy systems, clean hydrogen is burgeoning as an optimal alternative to fossil fuels, in which its application promising retarding global and environmental crisis. The evolution reaction (HER), capable producing high‐purity rapidly electrocatalytic water splitting, has received much attention. Abundant research about HER been done, focusing on advanced electrocatalyst design with high efficiency robust stability. As potential catalysts, metal nanoclusters (MNCs) have studied extensively. They are composed several a hundred atoms, sizes being comparable Fermi wavelength electrons, that is, < 2.0 nm. Different from atoms/nanoparticles, they exhibit unique catalytic properties due their quantum size effect low‐coordination environment. In this review, activity‐enhancing approaches MNCs applied electrocatalysis mainly summarized. Furthermore, recent progress classified different stabilization strategies, freestanding MNCs, organic, carbon supports, introduced. Finally, current challenges deficiencies these for prospected.

Abstract Electrochemically reducing CO 2 to more reduced chemical species is a promising way that not only enables the conversion of intermittent energy resources stable fuels, but also helps build closed-loop anthropogenic carbon cycle. Among various electrocatalysts for electrochemical reduction, multifunctional metal–organic frameworks (MOFs) have been employed as highly efficient and selective heterogeneous due their ultrahigh porosity topologically diverse structures. Up now, great progress has achieved in design synthesis active MOF-related catalysts reduction reaction (CO RR), corresponding mechanisms thoroughly studied. In this review, we summarize recent applying MOFs derivatives RR, with focus on strategies electrolyzers. We first discussed different RR products introduced commonly applied electrolyzer configurations current system. Then, an overview several categories (CO, HCOOH, CH 4 , 3 OH, multi-carbon chemicals) generated from or via was discussed. Finally, offer some insights perspectives future development reduction. aim provide new into field further guide research large-scale applications.

Main group single atom catalysts (SACs) are promising for CO2 electroreduction to CO by virtue of their ability in preventing the hydrogen evolution reaction and poisoning. Unfortunately, delocalized orbitals reduce activation *COOH. Herein, an O doping strategy localize electrons on p-orbitals through asymmetric coordination Ca SAC sites (Ca-N3 O) is developed, thus enhancing activation. Theoretical calculations indicate that Ca-N3 improves electron-localization around promotes *COOH formation. X-ray absorption fine spectroscopy shows obtained features: one three N coordinated atoms with as a reactive site. In situ attenuated total reflection infrared proves As result, catalyst exhibits state-of-the-art turnover frequency ≈15 000 per hour H-cell large current density -400 mA cm-2 Faradaic efficiency (FE) ≥ 90% flow cell. Moreover, retain FE above even 30% diluted concentration.
